Classification Decision Trees

• Heart Attack Analysis & Prediction based on Kaggle dataset.

  • age : Age of the patient
  • sex : Sex of the patient
  • exang: exercise induced angina (1 = yes; 0 = no)
  • ca: number of major vessels (0-3)
  • cp : Chest Pain type chest pain type
    • Value 1: typical angina
    • Value 2: atypical angina
    • Value 3: non-anginal pain
    • Value 4: asymptomatic
  • trtbps : resting blood pressure (in mm Hg)
  • chol : cholestoral in mg/dl fetched via BMI sensor
  • fbs : (fasting blood sugar > 120 mg/dl) (1 = true; 0 = false)
  • rest_ecg : resting electrocardiographic results
    • Value 0: normal
    • Value 1: having ST-T wave abnormality (T wave inversions and/or ST elevation or depression of > 0.05 mV)
    • Value 2: showing probable or definite left ventricular hypertrophy by Estes' criteria
  • thalach : maximum heart rate achieved
  • target : 0= less chance of heart attack 1= more chance of heart attack
